Unitree unveils H2-X with martial arts feats and 8-hour battery life

What changed for buyers

Unitree Robotics unveiled its H2-X humanoid robot on 21 October 2026. The new model is shown in a demo video performing martial arts moves, lifting a car, and jumping from heights marked as 4 meters. Unitree says the robot can stand for up to 8 hours, compared with the standard H2's publicly disclosed endurance of about 3 hours. Test conditions for both figures are unspecified.

The H2-X is based on the H2 platform. The base H2 costs $29,900 and has 31 degrees of freedom, but Unitree gave no price, availability or hardware specs for the H2-X.

The video, titled “H2-X Kung Fu Legend Guardian”, was released on 21 October. It shows the robot performing flips, kicks, and rescues. Unitree says the footage is real and has not been sped up.

What the maker says

Unitree says the H2-X has a maximum runtime of about 8 hours. This refers to standing time, not continuous activity. The company urges users to operate the robot safely and in a friendly manner.

The video labels some actions as “Extreme testing” and warns viewers not to imitate them. It also says people and robots should maintain a safe distance of at least 2–3 meters from one another during operation.

Unitree did not say how much of the H2-X’s behavior is autonomous versus pre-programmed or remotely controlled. The company also gave no details on torque, weight, or computing hardware.

How it compares

The H2-X is part of Unitree’s H-series, which includes the H1 and H1-2 models. The H1 is 180 cm tall, weighs 47 kg, and is listed at $90,000; Unitree nevertheless invites buyers to contact it for the actual price (though Unitree invites buyers to “contact Unitree for the actual price”) (Domobot model sheet). The H1-2 variant weighs about 70 kg.

Unitree’s smaller R1 model weighs 29 kg and costs from $4,900 (Domobot model sheet). It runs for about 1 hour and is aimed at developers and educators.

Compared to other makers:

• Atlas by Boston Dynamics offers 56 degrees of freedom and 4-hour runtime but is in preorder with no public price (Domobot model sheet).
• The announced 2023 Apollo is listed with a four-hour runtime and no public price; no runtime is given for Apollo 2 (Domobot model sheet).
• Kepler K2 offers 8-hour runtime and costs ¥248,000 (Domobot model sheet).

Still unconfirmed

• Price or availability of the H2-X
• Whether the robot is for sale or remains a prototype
• Hardware specs: weight, degrees of freedom, torque
• Autonomy level of the actions shown
• Test conditions for the 8-hour runtime claim
